I have a sbs 2003 with 10 local users and some more via vpn connection. Due to low internet speed I changed my ISP. I have not disconnected my previous ISP yet so right now I have 2 internet ready to be used.
The old internet connection is working fine but when I connect the new internet connection I do not have internet in my network. I received all information from the new ISP like IP, Primary DNS, Secondary DNS, Subnet Mask from the new ISP but do not know where and how to use them.
When I connect the new internet connection to a laptop directly, I have internet connection perfectly but when I connect the same cable to the network I do not have internet. In order to give you a picture of the setting, please note as below:
Cable Modem from comcase===>Linksys wireless router(WRT54GS)===>hub switch(Netgear JFS524)===>server and all local computers are connected to hub switch
I know that I have to setup ther linksys router with new ISP given information as well as my lan but do not know how to do it. Can you help me please?
